WCWS: mechanics?

[TexBlue]

While I was watching the umpires as much as the game, I thought they did a good job. In the UCLA-Stanford game, I thought the PU made several good calls at home. Now, that I've brought it up, when Cal State runner was called safe at home, then out, did they ever explain why she was out? They kept talking about the 3BU having a better angle on the ball. How about running out of the baseline to avoid a tag? That was my 1st impression, and I still believe that would have been a good call. Since I've now been blocked off the game,so other programs can air, I can't tell what's happening, so someone please let me know if they ever explained that.
